A Shocking Warning
A man walks up a museum, dressed in jeans and a t-shirt. The guard at the door informs him: "You can't enter here, sir. This museum has a strict dress code."
The man nods and returns to his car. He roots around looking for anything at all in his car to dress him up, but can't find anything. In his desperation, he wraps his jumper cables around his neck and returns to the guard at the museum entrance.
"I'm sorry. I couldn't find anything nice to wear, but I was able to put these jumper cables around my neck as a tie. Please, I'm begging you, can I come in now?"
The guard replies, "Well," he pauses for consideration, "Alright, just don't try to start anything."
